CTI - Differences between Deluxe Ocean and Superior Ocean view

We are so excited to be in the process of booking for April 2013!! We went to CN in Jan 2011 and loved it!! We are wanting to try CTI this coming April/13. Can anyone advise of what the difference between these two categories is? Is it just a location thing? I've looked at pictures of the rooms on Oyster and the Deluxe shows an upgraded sink/vanity area in the Deluxe category. Is this correct? Is the view better from the Deluxe room?

I am sure you have already booked by now, but we previously stayed in the Superior Ocean. It is secluded and your views of the ocean can be partially obstructed. However, the sink/vanity area was gorgeously tiled. We also never saw or heard anyone else while in our room.
The Deluxe should have a better view of the ocean.
We chose Premier Ocean for our trip this April due to the view of the island and being closer to everything.
If you haven't already, come on over to the CTI Meetup thread "April Amigos".
